This game was also tested in my STE with TOS 2.06 and 68HC CPU processor and worked fine.

Testing the STX and SCP dumps in STeem SSE seemed to not work 100% in that it skipped the intro section on disk 1. When I booted the disks in my STE disk 1 shows two intro sections whilst playing the Dr Who theme music. This did not happen in STeem SSE and it skipped to asking for disk 2 to commence playing the game.
